Construct for expressing monomeric streptavidin

Abstract

The present invention relates to a monomeric streptavidin-expressing gene construct and a host cell into which a recombinant vector comprising the gene construct has been introduced. The gene construct according to the present invention, after injected in vivo through a strain, may express streptavidin, thereby making it possible not only to monitor in real time the location of the strain or a cancer tissue pre-targeted by the strain by using a biotinylated diagnostic agent, but also to increase the cancer targeting efficiency of a biotinylated anticancer agent.
